There are several ways to solve a problem, but which method is best? How can you know which of these will be more beneficial to you? This guide will break down the details and show you how to make an informed decision.

What is 8D?

8D is a problem-solving technique used to identify and solve the root cause of a problem. It was developed by Ford Motor Company and was formerly known as Team Oriented Problem Solving or TOPS for short. The 8D process consists of eight steps:

  1. Build a Team: First, there should be members who can identify the issue and get the right people to work on it to solve the problem.
  2. Describe the Problem: Collect information about the problem in as much detail as possible. 
  3. Temporarily Solution to the Problem: Finding a solution to the problem and isolating it before looking for answers. The better the isolation, the less impact on product quality or customer happiness.
  4. Root Cause and Escape Point: Detect the root cause of the problem by researching all the contributing factors and finding out at which point the situation could have been prevented.
  5. Plan Corrective Action: After the root causes have been identified and verified, the next step is brainstorming ways to correct the problem permanently. There will also be a risk assessment.
  6. Implement Corrective Actions: The next step is to create an action plan. Then communicate it with all necessary parties.
  7. Implement Preventive Actions: The necessary management changes can be made promptly by communicating the new process.
  8. Praise Team Members: After a final review of the process and giving feedback to all team members, show appreciation for the hard work.


The DMAIC process is a structured approach to problem-solving that can be applied to any project or situation by reviewing the data to find the main cause of defects. The steps are:

  1. Define Research the nature of your problem and how it will affect you as a company.
  2. Measure: You should measure the extent of the problem
  3. Analyze: Identify the root cause that is the source of the problem.
  4. Improve: Brainstorm for solutions and put them into action.
  5. Control: Maintain the improvements you have gained with the solutions.

Should You Choose 8D or DMAIC?

After reviewing the steps involved in each one, how are you supposed to know which one is the right one? It depends on your situation. Both are effective in critical thinking and corrections. However, 8D is most effective for safety concerns, test failures, regulations, etc. It is a detailed process that can be prudent for business improvements. If your business requires an in-depth look, you’d want to use 8D. The most versatile option is DMAIC because the steps can apply anywhere. For example, you can use it for your website or repairing your house. You can also use it for business, but it will not offer as much as the 8D. The right one for you will be the one that aids in the fastest resolution to your specific problem.
